According to Dale S. Beach, Human resource planning is a process of determining and assuring that the organisation will have an adequate number of qualified persons, available at the proper times, performing jobs which meet the needs of the enterprise and which provide satisfaction for the individuals involved.
How much sleep do teens need? Based on current data, we think that most teens need on the order of 9-plus hours nightly to have optimal sleep. The NSF poll data indicate that most teens fall short of this goal, many by a considerable amount. Although we think that the need for sleep does not really change across adolescence, the amount of sleep young people get does decrease in older teens.
What to expect. Adolescents are notorious for not getting enough sleep. The average amount of sleep that teenagers get is between 7 and 7 Â¼ hours. However, they need between 9 and 9 Â½ hours (studies show that most teenagers need exactly 9 Â¼ hours of sleep). Teenagers do not get enough sleep for a number of reasons: Shift in sleep schedule. After puberty, there is a biological shift in an adolescentâs internal clock of about 2 hours, meaning that a teenager who used to fall asleep at 9:00 PM will now not be able to fall asleep until 11:00PM.
